IBM has won back the world supercomputer crown with the Sequoia, which has topped the most recent list of the 500 fastest supercomputers in the world. The race for supercomputer bragging rights is the 21st century’s version of the space race, both between companies and between countries, analyst Rob Enderle remarked. “But these bragging rights can open the door for billions of dollars in follow-on business.”

IBM’s (NYSE: IBM) Sequoia supercomputer has headed up the most recent Top500 list of the world’s fastest supercomputers.

The list, released on Monday at the 2012 International Supercomputing Conference in Hamburg, Germany, is compiled twice a year.
